Do you trust Zeus Quick Change?

Do you guys even know how shooting works,
What is “return to zero“ when you are changing calibers or barrels
I mean I have been running the AI system since before they were public, what is your “idea” of return to zero ?
Why do so many people think they can shortcut this process and be successful
is the Zeus any good, yes, does the barrel system work yes, now define “return to zero”?

Doesn’t matter, do you think changing a barrel profile, caliber or both will not have enough effect you should be rezeroing ?
People don‘t seem to understand barrel harmonics or recoil management very well.
If you were shooting a box of Hornady and ran out then moved to a box of Berger I would suspect one might need to zero even if the bullet weight was the same
Even .2 Mils is .72” at 100, so just leave it or fix it ?
The idea people have behind changing a barrel and having it be on target is crazy, good enough if you are lazy, sure, but I want you to define “good enough”

I have not seen that, your definition of “dead on” must be different from mine
They are like anything else, .1 or .2 but that is not dead on, are you describing take the same barrel on and off, cause that is smaller, but changing caliber is never dead on... sure you can pull a barrel put it back they are close but not perfect

Just know the difference, account for it and move on. This isn’t rocket science. Do you fly across the country and trust the same zero you had 1500 miles East with different altitude and parameters? No. You re-zero when you get go said location. Same with a quick change set up. You should always re-check where you are at. As mentioned above it will likely be good enough for most people but that depends on what certain variables are and how close you need/want it to be each time.

I don’t have a zeus, but a vector. So long as I stay within the same lot of my components I can switch between my 6creed and 308. Now, I do need to correct for the off set. I zero with the 6 creed, then spin on the 308 and note the difference. I has been repeatable for me.
I change barrels nearly every range trip at various distances without issue.

@SilentStalkr get it’s.You should probably care more on how close you can get it to return to zero vs actually returning to zero.
I’ve yet to witness a return to zero on the several quick change rifles I’ve got/ had. Maybe I’m doing something wrong, or maybe I just don’t care. Lol.
But I’ll always check zero regardless if the system is “dead on”.
I didn’t say “return to zero” in my OP at all. I asked about it holding zero. Quite a difference I’d think. I’ve heard issue of the barrel being bumped on a QC and it throwing off POI. So that’s more less what I’m asking. Some say if you full thread it then you won’t have that issue. Clearly I should of provided more info in the OP
Some say, who some
every single time a barrel failed to hold zero I personally observed were operator error
is that the some who say ?

Are you having a stroke little buddy?
No you just read about people asking something out of a system it’s not designed to do.
but it was clarified as holding zero after the fact, as noted each time I have seen it walk, it was usually operator error,
if these systems had a real problem considering what they cost, there would be endless threads crying about it. The lack of complaints might help answer the question

Thread was around here somewhere. Of course I can’t find it now. But someone tested hitting the barrel with a rubber mallet at 12,3,6,9 o’clock and the POI shifted. Mallet was used to simulate rifle being tossed around or barrel hitting a barricade when moving positions etc. I’ll keep searching but sounds like I should be good to go with a QD if that’s the route I end up taking
Just screw the barrel on with 100 ft/lbs and forget about it.
If you have doubts about the zero, just bimble down to your local spot and fire some rounds.
Would be more likely op error than rifle, surely?
Certainly don't believe that of AI.
Fuck, now my mind is set on snow.
Haven't been in it for ages.
I'll just go crawl into the chest freezer for a spell.

Those Colorado brownies have that effect!!!
I would think one would run a stage to see, artificially hitting something is never a true test
See that was my mistake should have eaten the brownie first

But, but, in the movies, the guy always takes a disassembled rifle out of a suitcase, screws it all together and makes the 1000 yd shot on the target, so...
I mean any QD system is gonna be a variable, so if there is anything on the line you want to do everything to protect yourself. Might be as simple as a witness mark, or even a drop of nail polish.
You have to recognize the limitations of the given system you choose, I use the AI because of the threads, I have shot with the screw undone and it still works to a degree. It takes a lot more to see it walk. Lots of threads...
The no threads can certainly be a factor if you don’t take extra care with the tightening of the screws.

Basically if you have the barrel shoulder up snug against the face of the action there is very little wiggle room for it to locate itself differently. The screws just hold it there.
I remember several tests for this and the barloc as well and if everything is cut correctly then it should be pretty stable and repeatable. It’ll be easy to rezero at least, you won’t be feet off in the dirt.

Do you even own a Desert tech. It clamps the barrel for like 12”.
I can switch between 556, 65cm, and 308 barrels and the offsets are the same always. R&R the barrel the zero stays exactly the same
The SRS uses an extension and then two screws, its like 3” not 12” Lol
Now we know why your wife can’t drive

I was pretty excited about the quick change feature when I bought my AI, thought I would be a quick change barrel swapping son of a bitch... Ive used it once when wore out my barrel.
Are you setting this up to be a switch barrel system or just keeping the one barrel and caliber? as @lowlight said, if there was an issue, you’d know it by now as there are quite a few out there. I’ve personally never heard anyone complain of a zero moving if installed correctly. I’m in the market for one of these myself. I’ll probably get the switch barrel option just because but I don’t plan on using that feature.
I run a WTO Switchlug with three barrels, mostly for hunting. Deer season rolls around I put barrel A on, after deer season it’s time to predator hunt so I put barrel B on. In the spring I put barrel C on just to plink and kill time. I rezero my scope after every barrel change. I never expected it to maintain POI every time especially since redoing the zero takes so little time.
I swap barrels between .223, 6 Dasher, and 243AI on a TL3. Some shouldered, some savage prefits with the nut loctited. I use a Ross Vice and an action wrench. The action stays in the chassis/stock and the scope never moves either. I have recorded the offsets between barrels. Frank is 100% correct. They are "repeatable." If I am trying to shoot a deer at 400 yds and in I will not have a problem. They repeat to within .2 mils. I never change barrels without refining my zero, though. Changing light and moisture conditions can cause optical effects that create poa/poi errors. If the error is doubled you could be off a long way. Typically with light effects I only see a .1-.2 offset. The most I have noticed is .3. If you add a .2 offset from changing barrels to a .2 offset from changing light conditions/mirage you are off .4. That puts you over/under even a large 2 moa target. It is super easy to check your zero. There is no reason not to check it and check it often.
Your post doesn't even make sense... If you already own a Zeus w/quick change then you can do the test yourself, and decide for yourself. I feel like I'm taking crazy pills reading this thread.
A hand tight Terminus Zeus will reliably hold zero until it is removed. If you remove, then reinstall a barrel, it it usually within .1 or .2 mils, sometimes less. I've never had it more than .2 mils.
It's a moot point though. Just as @Supersubes said, just torque the barrel on if you want. The QC version of the Zeus just gives you the option of hand tightening. The Zeus is a great action. Once you decide on a 60 degree throw action, there isn't a better option than a Terminus.
I have both a desert tech and Zeus. Surprisingly I haven’t seen too much of a difference between the two in terms of holding zero when removing a barrel and putting it back in. They are both within 0.1-0.2 mils. I thought the Zeus would be much more but it is not. That being said; it seems to take the Zeus 1 or 2 shots to settle back into zero but that could also be a cold bore thing, who know?
My Zeus does have a much bigger elevation shift when switching from one caliber to another than the Desert tech. The desert tech was closer to ~0.5 mils when switching from 223, 6.5CM, 308 and 338lm which is a surprise. My Zeus has a 1.1mil shift in elevation between 223 and the 6GT and they are the same length barrel and same contour. Lucky for me the windage is the same.

IMO with an AI, taking a barrel off and putting the same barrel back on, the zero will hold or be within the 0.1-0.2 mils that people keep mentioning. Mine tend to be within 0.0 - 0.1 mils.
Going from one barrel to a different one of a different cartridge/contour/length, its zero is generally within 1.0 mil. That's where documentation is important, you can record the offset and account for it easily in any number of ballistic calculators.
If you are shooting the Zeus with one barrel at a time, and shooting solely that barrel from new until it's shot out, I don't see the benefit of using their quick change tenon. Without dogging it or sounding like a complete AI fanboy, their system is essentially a small set screw, where the AI system is a clamp integrated into the action tenon threads which puts legit clamping force on the barrel. The longer tenon at 100 ft-lbs ain't going anywhere on the Zeus...if you have the ability to test it yourself prior to making the decision, it would be a great idea to test removing and re-installing the QC barrel multiple times to check if it holds zero, then to beat the barrel around while its installed to see if that causes the zero to shift as well.

Then say that, lol. Context is kind of important. You need work on your communication skills my man, haha.
I have a Zeus with quick change, it's a great set up. It gets banged around when I take it shooting and I have had no issues with maintaining my zero. I think it boils down to needs based on your intended use of it.

I run a vector action with the QC with 3 different barrels.
Once you are consistent with method it is pretty reliable.
Note your impact shifts and write them down.
Make corrections on your scope and you're usually within .1 or .2
I will admit at the beginning it took a while to get use to it.
